I purchased this Dac/amp last drop and love it. I've been thinking about getting the AKG K7XX headphones to use with it. I hear the K7xx can be picky about the amp that is used with it. Has anyone used the 2 together? Do you think it will be able to drive the K7XX?

I'm actually wondering the same thing... my iPhone doesn't do a great job of driving these headphones... I have the K7XX (the all black) and they are great cans... just not loud enough using most built in amp solutions
